Description

General description

Bcl-xL is a ~28 kDa member of Bcl-2 family of proteins and an important regulator of apoptosis. Bcl-xL forms heterodimers with BAX, BAK, and Bcl-2, and its overexpression in tumor cells confers resistance against chemotherapeutic drugs. Bcl-xL is phosphorylated on many sites including serine 62, a critical site for Bcl-xL response to microtubule-damaging drugs such as taxol and vinblastine. Phosphorylation of serine 62 (thought to be mediated by Jun N-terminal stress kinase (JNK) signaling) negatively regulates the anti-apoptotic function of Bcl-xL and controls the growth of neoplastic cells.

Specificity

Human Bcl-xL. Mouse and rat Bcl-xL (100% conserved) have not been tested, but are expected to react.

Immunogen

The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human Bcl-xL that contains serine 62. The sequence is conserved in mouse and rat.

Application

Anti-BCL-XL (pS62) Antibody detects level of BCL-XL (pS62) & has been published & validated for use in WB.

For Western blotting applications, we recommend using the antibody at a 1:1000 dilution.

Research Category
Apoptosis & Cancer

Research Sub Category
BCL2 & Inhibition

Quality

Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated Bcl-xL. The final product is generated by affinity chromatography using a Bcl-xL-derived peptide that is phosphorylated at serine 62.

Physical form

Dulbecco′s phosphate buffered saline (without Mg²⁺ and Ca²⁺), pH 7.3 (+/- 0.1), 50% glycerol, with 1.0 mg/mL BSA (IgG, protease free) as a carrier. 0.05% sodium azide.

Storage and Stability

Store at -20°C. We recommend a brief centrifugation before opening to settle vial contents. Then, apportion into working aliquots and store at -20°C. For shipment or short-term storage (up to one week), 2-8°C is sufficient.

Analysis Note

Control
SK-BR-3 cells treated with vinblastine.
